Table 4-1 Parameters of the ras.properties file used to configure direct dial.
Sec-
tion Parameter
Valid Values and
Default Values (in Bold) Description
General Properties
rasEnable true
false
Change this to true to enable RAS for this JACE-4/5. The modem will
not accept calls when this setting is false. In addition, when this is
false, the JACE will not attempt to initialize any attached modem.
Note: When using release 2.3, make sure to only set this to true
when you have a modem installed or attached. Otherwise the JACE
may be slow to boot. For an explanation, see the initFailLogOnly
parameter.
rasMode
directDial
captiveISP
Use direct dial for this function. Captive ISP mode is discussed in
Chapter 5, “Connecting to an ISP”.
dialOutOnly true
false
Set this to true and the JACE will not accept incoming calls.
General Properties
remoteAddr any valid IPv4 address in
dotted decimal notation
192.168.1.111
The IP address that is used by the remote machine dialing into the
JACE.
This address should
not be:
• on the same network as the address used to configure the JACE
with the Admin Tool (its LAN IP address).
• on any network reachable by the JACE through its LAN IP address
(if the JACE is also connected to a LAN).
• on any network reachable by the dial-in host through its LAN IP
address (if the dial-in host is connected to a LAN).
This address should be:
• an IP address on the same network as the localAddr parameter.
Setting up the address this way creates a unique network for dial-up
between the JACE and its dial-in host. This reduces the threat of
packets being routed the wrong way due to address conflicts.
localAddr
Note: In release
2.2, this parameter
is not listed in the
file. In release 2.3,
it is listed but
disabled by the
preceding # sign.
To enable the
parameter, remove
the # and supply a
valid IP address.
any valid IPv4 address in
dotted decimal notation
when parameter not listed
or disabled, defaults to LAN
IP address
The IP address that the JACE should use when talking to the
dialed-in host.
This address should
not be:
• on the same network as the address used to configure the JACE
with the Admin Tool (its LAN IP address).
• on any network reachable by the JACE through its LAN IP address
(if the JACE is also connected to a LAN).
• on any network reachable by the dial-in host through its LAN IP
address (if the dial-in host is connected to a LAN).
This address should be:
• an IP address on the same network as the remoteAddr parameter.
Setting up the address this way creates a unique network for dial-up
between the JACE and its dial-in host. This reduces the threat of
packets being routed the wrong way due to address conflicts.
Modem Configuration
Properties
device COM1
COM2
The COM port used by the modem. If using the JACE-4 internal
modem, this should remain at COM2. If using an external modem
with the JACE-4, this should match the serial port assignment of the
RS-232 port as listed in the port.properties file (see “Enabling the
JACE-4 Modem (Internal or External),” page 4-10).
